6J13 Foil thickness 0.01mm CuMn12Ni4 Manganin foil for Precision
Resistance Shunt
(Common Name: Manganin 43,CuMn12Ni4,Manganin )
Shunt Manganin 43 is a copper-manganese-nickel alloy (CuMnNi alloy)
for use at room temperature. The alloy is characterized by very low
thermal electromotive force (emf) compared to copper.
Shunt Manganin43 widely used for Shunt resistor with the highest
requirements, shunt manganin43 has been used in precision built
electrical components such as Wheatstone bridges, decade boxes,
voltage drivers, potentiometers and resistance standards.
